My 65 might have been a heater delete from the factory or either all heater components are just missing. I'm not interested in adding a heater but would like to plug the 5 to 6 inch hole under the dash on the pasensger side. The hole runs directly to underside of cowl vent. Ideally, I'd like to find an original style passenger side vent assembly w/ vent door. Does anyone know where I might find one? In unavailable or cost prohibitive, I'd like to just plug the hole. Does anyone have any suggestions on an easy way to plug the hole?
